Detecting Chiral Gravitational Wave Background with a Dipole Pulsar Timing Array
Baoyu Xu, Hanyu Jiang, Rong-Gen Cai +2
The pulsar timing array (PTA) is a powerful technique for detecting nanohertz gravitational wave backgrounds (GWBs). However, conventional PTAs lack sensitivity to parity violation…
Parameter extraction of the stochastic gravitational wave background with peak-like templates in millihertz
Heng-Sen Jiao, Hong-Bo Jin, Yun-Long Zhang
We investigate a framework for extracting parameters of stochastic gravitational wave background (SGWB) with peak-like templates in the millihertz frequency band, and analyzing tra…
Detectability of the chiral gravitational wave background from audible axions with the LISA-Taiji network
Hong Su, Baoyu Xu, Ju Chen +2
The chiral gravitational wave background (GWB) can be produced by axion-like fields in the early universe. We perform parameter estimation for two types of chiral GWB with the LISA…
Alternative LISA-TAIJI networks: Detectability of the Parity Violation in Stochastic Gravitational Wave Background
Ju Chen, Chang Liu, Yun-Long Zhang +1
The detection of parity violation in the isotropic stochastic gravitational wave background (SGWB) will serve a crucial probe for new physics, particularly in parity-violating theo…
Chiral Gravitational Wave Background from Audible Axion via Nieh-Yan Term
Baoyu Xu, Keyi Ding, Hong Su +2
Axions and axion-like particles can be probed through gravitational waves indirectly, often referred to as "audible axions". The usual concept of audible axion relies on the coupli…
Circularly Polarized Gravitational Wave Background Search with a Network of Space-borne Triangular Detectors
Ju Chen, Chang Liu, Yun-Long Zhang
Circularly polarized gravitational wave backgrounds are predicted in many well-motivated models of inflation and phase transitions involving spontaneous parity violation. In this w…
